[BioC] ExpressionSet or MAList

[Daniel Brewer]

Hi,

I am starting to think about grouping a series of microarray datasets
into bioconductor objects so that I can quickly look to see how a gene
behaves in each dataset.  The two main options seem to be to use
ExpressionSet or Limma's MAList.  Has anyone got an opinion on which
would be best to use or the advantages and disadvantages of both.

To my mind MAList stores the annotation with the dataset which I feel is
an advantage whereas ExpressionSet is the base implementation for many
libraries.
